Abstract
The utility model relates to a hydraulic penetrating type impactor, belonging to a boring rig of water power reverse circulation continuous core taking, used for hydrology, engineering and geological exploration. The utility model is mainly composed of a movable valve, a ram, a throat ring, a through hole, a breathing hole, a reverse circulation continuous core taking drill bit, etc. A matching double wall drill rod realizes impact rotation, water power reverse circulation and continuous core taking into one body. The utility model improves the condition of rock blasting, enhances the service life of the drill bit, effectively prevents rock core from blocking, and is favorable to constructing in complex geologic body; the utility model has the advantages of long round trip meterage, high efficiency for drilling, and the good quality of rock core (sample) taking.
Description
The utility model relates to a kind of hydraulic reverse-circulation continous sampling drilling tools that is used for the hydrology, engineering and geological prospecting.
Disclosed a kind of anti-circulation continous sampling impactor and packer in CN86104172A, its purpose are preventions and alleviate the core obstruction, improve drilling efficiency.Its major technique is the sealing ring of being made by hollow type reverse circulation impactor, polytetrafluoroethylene (PTFE) and does not have in relative rotation with hole wall that packer constitutes.The anti-continous sampling probing that circulates of impact machine device though the drilling tool of this structure might be realized surging, but it is easy to wear by the sealing ring that polytetrafluoroethylene (PTFE) is made, packer is fragile, can't avoid card stifled fully in troublesome zone drilling, and complex structure, be difficult for processing, cost is higher, use simple and conveniently not enough, bring certain difficulty, influenced the performance of this method superiority to construction.
The purpose of this utility model just is to provide a kind of impactor that can overcome above-mentioned shortcoming, cooperates the disclosed anti-circulation continous sampling drill bit of CN1055792A, the sealing ring and the packer that do not need polytetrafluoroethylene (PTFE) to make.Simple in structure, cost is cheap relatively, and is easy to use, solves the stifled problem of complex stratigraphic drilling core card effectively.
The utility model is to realize by the special construction of anti-circulation continous sampling drill bit and impactor, and impactor is provided with straight mouthful 2 of top connection, top annular groove 3, interior pipe 4, middle part anchor ring 5, anchor ring shoulder 6, interior spray-hole 14, straight mouthful 15 on drill bit, following spiracle 17 and last spiracle 18.
The utility model can also be realized by following measure: all adopt metallic seal between each mutual moving parts, the metallic seal surface is provided with the helicla flute of square-section along axis direction, so that impurity in the exhaust fluid; The bottom of outer tube 10 and top are respectively equipped with spiracle 17 and 18; Through hole 16 diameters are 1:2 with impactor external diameter ratio; In pipe 4 impactor inner body and central passage is isolated, interior pipe 4 tops connect with double-wall drill pipe, insertion drill bit in bottom is directly in the mouth 15.
Through indoor bench test, realized that impact rotating, hydraulic reverse-circulation and continous sampling three technology in one, have improved broken rock condition and mechanism.The unexpected keying of valve because impactor is lived, the pulsatile impact of generation pressure, surge pressure help to solve the stifled problem of continous sampling drilling core card, make core drain into the face of land smoothly.Especially to consolidating stratum, can improve drilling efficiency and footage per round trip length by a relatively large margin, prolong drilling life of bit, solve the anti-stifled problem of core card in the continous sampling probing of following effectively.
The drawing explanation of accompanying drawing:
Fig. 1 is the through impactor side cutaway view that surges: 1 top connection, straight mouthful of 2 top connections, 3 top annular grooves, pipe in 4,5 middle part anchor rings, 6 anchor ring shoulders, 7 valves alive, 8 valve radial holes alive, 9 block stamps, 10 outer tubes, 11 hammering blocks, 12 restrictor rings, 13 anti-circulation continous sampling drill bits, 14 interior spray-holes, straight mouthful of 15 drill bits, 16 through holes, 17 times spiracles, spiracle on 18.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing: the supporting use of through impactor and double-wall drill pipe of surging.Double-wall drill pipe connects with through impactor top connection 1 top of surging by screw thread, and interior pipe 4 is seated in the straight mouth 2 of top connection, is suspension status.Top connection 1, outer tube 10 and interior pipe 4 formations valve alive work chamber about in the of 7, the valve 7 of living places chamber, the valve 7 middle part anchor rings 5 of living place in the top annular groove 3 of outer tube 10, the motion of 6 pairs of valves 7 alive of anchor ring shoulder plays the axial limiting effect, decision valve 7 movement travels of living, in the top annular groove 3 liquid mediums by on exhale hole 18 to communicate with the impactor external agency.Block stamp is two ends diameter difference about in the of 9, up-small and down-big formation area difference, and constitute metallic seal with outer tube 10, following spiracle 17 and impactor external communications respectively.Outer tube 10 bottoms connect with hammering block 11 with spline, in order to transfer torque and the axial impact force of freely transmitting.Restrictor ring 12 places hammering block 11 lower surfaces and anti-circulation continous sampling drill bit 13 to compress.Insert in the straight mouth 15 of drill bit interior pipe 4 bottoms, formation through hole 16.The hydrodynamic medium is imported by double-wall drill pipe, and the annular gap between top connection 1 and interior pipe 4 enters impactor.Live when initial valve 7 and block stamp 9 is in the nextly, and fluid flows to the continuous coring bit 13 of anti-circulation connection through the valve radial hole 8 of living, block stamp 9, interior pipe 4 and annular space and restrictor ring 12 between the hammering block 11, and liquid medium makes the pressure rising when flowing through restrictor ring 12.The area difference of chamber up and down of valve 7 alive and block stamp 9, valve 7 alive is at first transported risen to top dead-centre, after rising bump valve 7 alive, block stamp 9 closed fluid medium channel, impel pressure pcl so to raise, valve 7 alive and block stamp 9 move downward rapidly under this high pressure effect simultaneously, live valve 7 because of the little at first stop motion of stroke, the valve 7 of living is separated with block stamp 9, fluid media (medium) forms path again, block stamp 9 continues to move downward bump hammering block 11 under the effect of inertia force and gravity, promote anti-circulation continous sampling drill bit 13 broken rocks, finish one-shot.Fluid media (medium) after work spray-hole 14 in anti-circulation continous sampling drill bit 13 and interior pipe 4 bottoms drains into through hole 16.
